HP stopped offering drivers for Windows 9x and Windows ME quite some time ago. The first step in getting help with locating drivers is to id the hardware. If you're unable to do so, then I suggest this program:

To find make and model of pc hardware, EVEREST Home Edition is a free system diagnostics, system information program that will id most hardware onboard a mb. as well as the actual motherboard.

Also, you can use your favorite search engine and look for drivers posted on other sites. You would need to type the model number into the search engine box. I found a couple of drivers (on the first Google page) for this model.
